The lead battleship is either the Yamato or the Musashi. They were the only Japanese battleships to have three gun main turrets. Since there isn't a tag for the Musashi, or any real way to tell the two apart visually, I'll just tag it Yamato.

The trailing vessel appears to be one of the four Kongo class battleruisers. Again, there is no visual way to tell them apart except in a detailed picture, but as there isn't a tag for the Kongo I guess this doesn't matter too much.

Tags confirm that lead ship is the Yamato and background ship is the Nagato.
